Citation Needed... LOL!
Yeah, I didn't take the time to actually find the real source. But if Wikipedia says it, it must be true.
-wtk
and yet I can't convince my english teacher to let me cite it as a source in my research paper
Well you could quote wikipedia as a rumor.
Allthough I like boromir a lot to me he can´t be the most favourite, because he ain't the most important character. The most important character is the ring in which Sauron's essence is embodied. And everybody in the story can't resist (except for Faramir, who was cooler in the book then in the film; And
Tom Bombadil, who wasn't even in the film) the ring so he's the most popoulair

And we can't resist the ring either otherwise we wouldn't play this fabulous game

Definitely: Sauron is the most populair character.
